Associated Spring Raymond 103-718 Die Spring Blue

Product Description

The ASSOCIATED SPRING RAYMOND 103-718 is a medium-duty die spring engineered for use in stamping dies, punch presses, and industrial tooling applications. It features a 1-1/2 inch hole diameter, a 3/4 inch rod diameter, and a 4-1/2 inch free length. Constructed from chromium alloy steel with a trapezoidal wire profile, it delivers consistent spring force and extended service life under repetitive compression cycles. The blue color coding indicates medium-duty load classification, allowing tool and die makers to quickly identify the correct spring for a given application. Maximum deflection load is 517.5 pounds at 2.25 inches of travel.

This die spring is suited for industrial manufacturing environments where dies, molds, and fixtures require reliable return force. It is commonly installed in stamping and forming dies in both production tooling and maintenance-repair applications. The trapezoidal wire cross-section increases load capacity relative to round-wire springs of similar dimensions, making it appropriate for medium-duty press work and fixture design. Tool and die technicians and industrial maintenance professionals are the typical installers.

Key Features

• Medium-duty blue color coding for quick load-class identification on the shop floor
• Trapezoidal wire cross-section for higher load capacity than standard round-wire die springs
• Chromium alloy steel construction for durability under repetitive compression
• 517.5-pound maximum deflection load with 2.25 inches of maximum deflection
• Spring rate of 230 pounds per inch for predictable, linear force output
• ISO 9001:2008 and ISO/TS 16949:2009 certified manufacturing

Compatibility

Designed as a standard medium-duty die spring for use in stamping dies, punch presses, molds, and industrial fixtures requiring a 1-1/2 inch hole diameter and 3/4 inch rod diameter.

Installation Notes

Installation is typically performed by tool and die technicians or industrial maintenance personnel during die assembly or press maintenance. Confirm rod and bore clearances match the 3/4 inch rod diameter and 1-1/2 inch hole diameter before installation. De-energize and lock out all press or tooling equipment before servicing die components. Do not compress the spring beyond its rated 2.25-inch maximum deflection to avoid permanent set or fatigue failure.
